Whatman 10334551 Grade 0860 1/2 Qualitative Filter Paper Folded (Prepleated), 240 mm, 100 per pack

Time-saving Whatman qualitative grades are offered in this convenient form, which gives major advantages over flat circles.

Comparable to Grade 858 but with a smooth surface, slightly thinner and faster. Also available flat stock form as Grade 86.

Features:

• Savings in time required to quadrant-fold circles to fit conical Filter funnels in repetitive or multiple analysis.
• Decreased overall filtration time because of the extra surface area exposed; the normal slow down of filtration speed due to the loading of Particulate is postponed.
• Increased total loading capacity as more Filter area is available.
• Maintained flow rate due to the reduction in Filter paper contact with funnel side and the self-supporting shape of the Filter itself.
• The prepleating does not significantly affect any of the technical data, and the same figures may be used for the flat circles.
